How do you show that:

[tex]\delta(q' - q) = \frac{1}{2\pi} \int dp e^{i p (q' - q)}[/tex]

with δ as the Dirac delta, q and q' as two position eigenstates, and (I'm only guessing) p as an iterator over the set of momenta.

I'm not sure the relationship between q and p that makes this work and I'm also not sure where that [tex]\frac{1}{2 \pi}[/tex] factor comes from.
